In the publication above alluded to the author states this species 

 to be closely related to Platycerus depressus, Leconte, with which 

 species P. Oreg07iensis, Westwood, is perhaps identical,

I am indebted to M. Fairmaire for the addition of this new 

 species (of which I have also seen a specimen in the collection of 

 Alexander Fry, Esq.) to my cabinet ; it is allied to S. femoralis, 

 Guerin, but at once distinguished from it by its more depressed 

 and less punctate elytra and less rounded apex of those organs, 

 the more clearly defined and narrower longitudinal pale yellow 

 lateral vitta above mentioned, and, finally, by the legs being black 

 instead of rufous. The female, as is usual in this genus, differs 

 in having short, coarsely punctate mandibles (which, in the pre- 

 sent instance, appear to be totally unarmed), and in the minute 

 size and strong punctuation of the head.
